Because the smooth muscle layer is thicker in arteries than in veins, which of the following is a logical conclusion?

select one:

a. arteries need more muscle than veins because the function of arteries is more important than the function of veins is.

b. arteries are more fragile than veins and need to be protected with more muscle.

c. the function of arteries depends on constricting smooth muscles, whereas the function of veins does not.

d. arteries and veins serve similar functions in most organisms.

-based on your observations of skeletal muscle tissue in experiment 3, which of the following describes characteristics of skeletal muscle tissue?

select one:

a. the fibers are not striated and cells are indistinguishable from each other.

b. the fibers are striated and have multinucleated cells.

c. the fibers are striated and each cell has a single nucleus.

d. the fibers are not striated and do not run in an observable direction.

-were you able to observe any nuclei or other internal cell structures in the outer skin surface slide? how is the presence or absence of nuclei consistent with what you know about the outer skin surface?

-what type of cells did you see in the dermis and epidermis image? describe them and id the type of cell.
